The bolt is basicly 2 main parts & a spring. The first part is what connects to the striker & the second is an outer sheel the touchs the body & pushs the ball. When the ball is not in the chamber all the way, the outer piece will stop on the ball but the inner piece will keep cycling to recock the marker.

you have to pull the cockin rod up on the stock bolt to slide it in and out. when the cocking rod is pulled up you can slide the bolt in and then when it's in place you push it down to lock into the striker. The gun does not work with this bolt http://www.shocktechusa.com/pages/ma...fbolt_long.htm
it doesn't work with that because the little metal stub at the bottom hits the body of the gun when you slide it in.

it is a top cocking gun.

please give me bolts that will actually fit.... it is the spyder classic one. Both of those you reccomended will not fit.
